Differentiate, distinguish, compare and explain what is the main differences between intrinsic and extrinsic semiconductors.

Comparison and Differences between Intrinsic and Extrinsic Semiconductors

  • Intrinsic are pure semiconductors. Extrinsic are impure semiconductors.
  • In first, conductivity is poor. In second the conductivity is large.
  • In intrinsic semiconductors, the number of electrons and hoes are equal. In Extrinsic semiconductor, n-type electrons are in majority whereas in p-type holes are in majority.
  • In intrinsic Fermi energy level lies at the center of forbidden energy gap. In other, n-type Fermi level lies near the bottom of conduction band and in p-type near the top of valence band.
